Diagnosis of a Trocar Site Mass as Omental Herniation after Laparoscopic Gastrectomy

A trocar site hernia is a rare complication. We report a patient who had an abdominal wall mass at a previous trocar site after laparoscopic distal gastrectomy. It was diagnosed as omental herniation and fat necrosis. We conclude that patients with trocar site masses exhibiting fat density on a computed tomography scan could be followed up without surgery, and that fascial defects located at 10-mm or larger trocar sites should be closed whenever possible to prevent hernia formation.

A Case of Congenital Epulis of the Newborn

Congenital epulis of the newborn refers to a very rare gingival tumor that occurs along the anterior alveolar ridge in newborn infants. We report a neonate with 3*2*1.5cm mass protruding from the mouth. This was a pinky, red solid pedunculated mass, attached to the maxillar left canine region of the alveolus at birth. The tumor's large size partially obliterated the oral cavity and caused oral feeding difficulty but did not cause respiratory problems. We described the postnatal MR imaging findings, electromicroscopic, histochemical and immunohistochemical studies of this tumor in order to search for the histogenesis of the tumor. In our case, histochemically, individual tumor cells contained numerous PAS positive cytoplasmic granules. Immunohistochemically, strong and diffuse cytoplasmic staining for vimentin and NSE was observed. Staining with S-100 protein, cytokeratin, desmin, CEA, factor VIII-related antigen, lysozyme, EMA were negative. After total excision of the lesion in our case, we had no complication or recurrence either early or late(up to one year).

Primary Osteosarcoma of the Breast: A case report

We report a case of primary osteosarcoma of the breast which is rare and exhibits poor prognosis. A 52 years-old-woman was admitted with rapidly growing right mammary mass. A huge lobulated dense mass with speckled calcifications, suggesting malignancy, was observed on mammography. She underwent a radical mastectomy. Grossly, the mass measured 16 14 6 cm and showed grayish white hard lobulated tissue with focal hemorrhage and necrosis. Light microscopically, the tumor was confirmed as an osteosarcoma devoid of any epithelial components. In postoperative whole body bone scan, there was no evidence of the other malignancy. To the best of our knowledge, the present case is the first report of primary osteosarcoma of the breast in Korea.

Breast Carcinoma Following Silicone Injection

A 57-year-old woman developed an inflammatory carcinoma in her left breast next to the spot of a silicone injection that had been used for augmentation some 20 years previously. She underwent a modified radical mastectomy with an axillary lymph node dissection. There have been relatively few cases reported in the literature that have noted breast cancer associated with silicone injections. During physical examinations, such breasts are frequently firm, tender, painful, and inflamed. Far more important, in silicone-injected breasts, carcinomas become more difficult to detect by physical examination, mam mography, and other known methods. Although no causal relationship between silicone and breast carci nomas is implied, a heightened awareness of the possible coexistence of silicone mastopathy and a breast carcinoma is necessary.

Fine Needle Aspiration Cytology of Clear Cell Sarcoma: A Case Report / 대한세포병리학회지

Clear cell sarcoma(CCS) is an uncommon soft tissue sarcoma that occurs in tendons and aponeuroses, usually of the lower extremities and is believed to be of neural crest origin that have a capability to produce melanin. These tumors commonly metastasize and have a very poor prognosis. The fine needle aspiration cytologic finding of CCS is not well documented. We recently experienced a case of CCS. The patient was a 54-year-old male with painful swelling of the right inguinal area. Fine needle aspiration cytology revealed polygonal or fusiform tumor cells with clear or granular cytoplasm and vesicular nuclei containing one or two nucleoli. Im munohistochemical staining for S-100 protein and HMB-45 revealed strong positivity, and variable developing stages of premelanosomes were observed by electron microscopy in the excised specimen.
